Developing a PC-Based Communications System using TAPI and Visual Basic

Abstract / Excerpt:

This study aimed to develop an efficient PC-based communications system that will address the concerns of business-minded people, and active modem users as well when it comes to interacting with other people. The study aimed to achieve this objective by having a prototype program as a technical output that combines the functionalities of standard and advanced communication devices, as well as the standard and advanced telephone services being offered by Telephony Service Providers, or TSPs. The prototype program was created utilizing TAPI (Telephony Application Programming Interface) technology, with an add-in made by the proponents on this technology and improvements on some of the telephone services as well. Significantly, this study also aimed to find out if the prototype program could .fully support the Caller ID service even without subscribing for such service from any TSP. The standard and advanced communication devices integrated for the prototype program were the Answering Machine, Fax Machine and of course, the ubiquitous Telephone. The fax machine aspect of the prototype program however, only succeeds on the sending end. As for the standard and advanced telephone services supported, these were Speed Dial and Caller ID, with the latter containing Audio Information about the caller. However, it was found out that Caller ID is not fully supported without subscribing for such service from a TSP. The prototype program also supports Ringer Tones, a prevalent cellular phone feature. Because of this feature, there was a conflict with the Audio Information feature of Caller ID and was only resolved by bypassing this feature if Caller ID information is present. Lastly, a Phone Book was integrated with the prototype program for functional and aesthetic purposes.
